Review on 47861 Powermaster Alternator by Hunter Siemon

Revainrating 5 out of 5

Alternator output increased from 105 to 140 amps

Insufficient direct mount for my application (93' K1500 5.7L), I had to 'reset' the housing (E8 1/4" drive socket and pulley removal requires a 1/2" 24mm wall thickness drive socket + 1/2" drive impact wrench). Slide rails, threaded mounting holes in housing are 8 x 1.25 threads, PowerMaster requires the addition of a new larger "charge positive" cable (I have 4 gauge used / minimum 8 gauge recommended) and adding the alternator to the engine "ground" wire (I used 4 gauge directly to the negative battery terminal) Capacitor on the driver's side (1230cc A/C on High No more battery drain, very satisfied.

Pros
  • great product
Cons
  • Some issues
